Clay Stamp

This is a stamp I designed to stamp ceramics/clay/pottery with a logo or design.

I have made it with a personalized logo that wont be downloadable, but can be seen in the pictures.

I uploaded an empty design that can be edited in your slicer or directly through the onshape link I will provide below.

Basically, you should emboss your own design on the biggest of the two circular sides. The best height of the design is 2mm. It can be .6 or .4mm thick (.6 is sturdier, but more difficult to stamp partially dried clay, like with clay pouring)

You can also deboss .1mm on the smallest circle to create a multicolor version with the design visible on the handle part of the sstamp. (Like in the pictures)
Printing in 2 colors can be achieved without a MMU, by setting your printer to swap colors every layer. I will provide the explanation for the method below.

When asked, I could add some simple designs and upload them for you. (Like a shape or letters)

Printing instructions:
.2mm layer height is fine
Print with the handle on the print bed, no supports are required because oof the chamfer under the stamp head.
I use 3 perimeters, 5 top and 4 bottom.
Infill can be your preferred setting, I use 15% cubic infill.
For a smoother deboss you can use ironing.
If uncertain about bed adhesion, you can use a brim.

Multimaterial printing without MMU (I learned this method from another model here on printables, but don't know the original inventor of it):

Setting up Prusa Slicer
I would advice creating a “new” printer profile for this.
In Prusa Slicer go to the "Printer Settings" tab.
In the "Printer Settings" tab go to "General" settings.
Under "Capabilities" increase the number of extruders to the number of colors you want to print.
For each extruder you will get an entry on the settings list on the left ("Extruder1", "Extruder2", "Extruder3", ...).
I would recommend to change the "Extruder Color" under "Preview" in the extruder settings for each extruder. This is not important but it will give you a better preview of the result making life a bit easier.
In the "Custom G-code" settings add "M600" to the "Tool change G-code" (M600 is the G-code command for a manual filament change).
Setting up you print
Select the fake MMU printer profile.
Using the paint feature in prusaslicer, color the surface of your deboss in the 2nd color.
You can use smart fill and right click to apply the secondary color.
Hit "Slice now" and check the the color your printer will start with using the layer slider.
Transfer the G-code to your printer.
Printing
Whenever your printer reaches the M600 command it will pause outside the print area and prompt you to switch filament (supposedly your printer supports the M600 G-code command). It might ask for a filament change after doing the calibrations, just remove and reinsert the filament.

Some Tips
You can follow the layers and colors in your slicer with the layer slider on the right and bottom to check what color is next.

Prusa Slicer UI.
The printer might extrude a bit of filament right after you confirm completion of the filament change to build up nozzle pressure. To avoid this extruded filament to be be dragged over to your print and make a mess don't remove the filament that is extruded during the filament change, so it will be easier to grab the whole thing. Before confirming completion of the filament change get ready to pull the filament waste away when the print head starts moving.
This all probably sounds more complicated then it is. Once you understood how it works it's actually pretty straight forward.

I provided a 3mf, it might contain the MMU settings, I am unsure, please let me know.

Feel free to ask any questions you might have.
If you like my designs, consider letting me know by saving or rating it.
